Abstract: This article presents the results of experimental research on thermal destruction of finishing building materials and a hazard
assessment of the process. Thermal destruction of finishing materials was investigated by thermal analysis and the risk of the process
was assessed by infrared spectroscopy of gaseous products resulting from thermal destruction. The thermal analysis was carried out
by dynamic thermogravimetric analysis on the synchronous thermal analysis instrument NETZSCH STA 449 F3 Jupiter, which
makes it possible to detect changes in mass and heat flow from temperature. The heating of the samples was carried out at a rate of
10 ℃/min in the atmosphere with a consumption of 100 ml/min. The gaseous products formed during thermal destruction were
analyzed by infrared spectroscopy on IR-Fourier spectrometer «FSM 1201» with gas cell TGA 100 at wavelengths of 600-4500 cm-1.
The results of the study led to the production of TG, TFG and DSK curves, describing respectively the loss of sample mass, the rate
of mass loss and the change of heat flow from temperature as well as infrared spectra of products of thermal destruction of finishing
building materials at various temperatures. It has been found that the finishing building materials, when thermally disrupted, form
various chemical compounds, some of which are dangerous to the human body.
